Lantana plant named ‘Robpatgol’

ABSTRACT

A new and distinct cultivar of  Lantana  plant named ‘Robpatgol’, characterized by its upright and outwardly spreading plant habit; uniformly mounded plant form; semi-compact growth habit; freely branching habit; short internodes; dense and bushy habit; freely and continuously flowering habit; and flowers that are bright golden yellow in color.

Botanical designation: Lantana camara.

Cultivar denomination: ‘Robpatgol’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana camara, and hereinafter referred to by the cultivar name Robpatgol.

The new Lantana is a product of a planned breeding program conducted by the Inventor in Grain Valley, Mo. The objective of the breeding program is to create new semi-compact and freely-flowering Lantanas with attractive flower coloration.

The new Lantana originated from a cross-pollination made by the Inventor in August, 2001 of a proprietary Lantana seedling selection identified as code number 99-CRM-TC1, not patented, as the female, or seed, parent with the Lantana cultivar Golden Plume, not patented, as the male, or pollen, parent. The new Lantana was selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in a controlled environment in Grain Valley, Mo., on the basis of its semi-compact growth habit and attractive flower coloration.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Grain Valley, Mo., since September, 2002, has shown that the unique features of this new Lantana are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Robpatgol have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture such as temperature and light intensity, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Robpatgol’. These characteristics in combination distinguish ‘Robpatgol’ as a new and distinct Lantana cultivar:

-   -   1. Upright and outwardly spreading plant habit; uniformly         mounded plant form.     -   2. Semi-compact growth habit.     -   3. Freely branching habit and short internodes, dense and bushy         habit.     -   4. Freely and continuously flowering habit.     -   5. Flowers that are bright golden yellow in color.

Plants of the new Lantana can be compared to plants of the parents. In side-by-side comparisons conducted in Grain Valley, Mo., plants of the new Lantana differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Lantana were stronger and faster growing         than plants of the female parent selection.     -   2. Plants of the new Lantana were larger than plants of the         female parent selection.     -   3. Plants of the new Lantana and the female parent selection         differed in flower color as plants of the female parent         selection had creamy white-colored flowers.

In side-by-side comparisons conducted in Grain Valley, Mo., plants of the new Lantana differed from plants of the male parent, the cultivar Golden Plume, in the following characteristics:

-   -   1. Plants of the new Lantana were more compact than plants of         the cultivar Golden Plume.     -   2. Plants of the new Lantana were more freely branching, had         shorter internodes and were more dense than plants of the         cultivar Golden Plume.     -   3. Plants of the new Lantana had darker green-colored foliage         than plants of the cultivar Golden Plume.     -   4. Plants of the new Lantana were more freely flowering than         plants of the cultivar Golden Plume.     -   5. Plants of the new Lantana had more golden-colored flowers         than plants of the cultivar Golden Plume.

Plants of the new Lantana can also be compared to plants of the Lantana cultivar Robpatsun, disclosed in U.S. Plant Pat. No. 10,885. In side-by-side comparisons conducted in Grain Valley, Mo., plants of the new Lantana differed from plants of the cultivar Robpatsun in the following characteristics:

-   -   1. Plants of the new Lantana were more upright than and not as         cascading as plants of the cultivar Robpatsun.     -   2. Plants of the new Lantana had darker green-colored foliage         than plants of the cultivar Robpatsun.     -   3. Plants of the new Lantana had more intense golden         yellow-colored flowers than plants of the cultivar Robpatsun.
